How can I smooth out and unlock the movement with the input system?

I'm a beginner to unity and I'm trying out the input system. https://gyazo.com/27409be10a2508c75b381c2f4538a82f This is whats happening. . . . . using System; using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.InputSystem;

public class PlayerMovement : MonoBehaviour { private PlayerInputs controls;

 public float moveSpeed;
 public Rigidbody2D rb;
 Vector2 movement;


 private void Awake()
 {
     controls = new PlayerInputs();
 }

 private void OnEnable()
 {
     controls.Enable();
 }

 private void OnDisable()
 {
     controls.Disable();
 }

 private void Update()
 {
     movement = controls.Controls.Movement.ReadValue<Vector2>() * moveSpeed;
     transform.position = movement * Time.deltaTime;
 }

 private void FixedUpdate()
 {
     rb.MovePosition(rb.position + movement * moveSpeed * Time.fixedDeltaTime);
 }

}
